SPECIFICATION forming part of Letters Patent No. 728,224, dated May 19, 1903.

Application filed October 16, 1902. Serial No. 127.551 (No model.) I

T0 at whom it may concern:

Be it known that I, GEORGE W. GREEN-' WOOD, a citizen of-the United States of America, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and usefullmprovem'ents in Laterally-Adjustable Side Bearings for Slides or Reciprocating Members; and I hereby declare the following to be a full, clear, and-exact description of theinvention, such as will enable others skilled in the art to which it pertains to make and use the same. V

This invention relates'to improvements in laterally-adjustable lateral or side bearings for slides or reciprocating members.

The object of this invention is to provide a simple, conveniently laterally-adjustable, durable, and efiicient lateral bearing; and with this object in view and to the end of realizing other advantages hereinafter appearing said invention consists in certain features of construction and combinations of parts hereinafter described, and'pointed out in the claims.

In the accompanying drawings, Figure I is a top plan of a slide, the support for the slide, and a laterally adjustable side'bearing embodying said invention. Fig. II is a vertical section on line II II, Fig. I, lookingin the direction indicated by the arrow. Fig. III is a vertical section on line III'III, Fig. I, looking in the direction indicated by'the arrow. Fig. IV is a vertical section on line IV IV, Fig. I, looking in the direction indicated by the arrow. Fig. Vis a top plan in section 611 line V V, Fig. II. Fig. VI is a vertical section on line VI VI, Fig. II, looking in the direction indicated by the arrow. Fig.VII is a vertical section on line VII VII, Fig. II, looking in the direction indicated by the arrow.

Referring to the drawings, a designates the bed of the machine,which comprises a slide Z2, which is supported from and is adapted to travel in'the said bed. The bed a next below the slide 1) forms the bottom of the slideway, which is formed in the bed and engaged by the slideb, and'the bed-is provided at one side of the path of the slide with an upright guide-forming wall 0, which extends along the said path and forms one of the side walls of the aforesaid slideway. The bed a at the opposite side of the path of the slide is provided with a vertically-arranged lat-erally-ad- 'justable plate 01, which extends along the said travel and affords lateral bearing to the said side of the slide. The lateral adj ustability of the plate (1 renders the said plate capable of being readjusted to take up any :wear occasioned between the said plate and the slide, and suitable means, as will hereinafterappear, is provided for securing the said plate in the desired adjustment.

A vertically-adjustable plate e is arranged at the outer side of the laterally-adjustable plate d, between the latter and an upright wallf of the bed, a.

The slide 1) is provided at the bottom with a flange b, which extends in under the plates at and c and longitudinally of the slide and is instrumental in preventing upward displacement of the slide.

The wall f isprovided at the top with a plate 9, which is arranged horizontally and secured to the top of the said wall by studs and nuts or other fastening devices,"as at h. (See Figs. I,'II,an'd VI.) The'top'plate g is preferably set into and snugly engages a recess f, which is formed in the top of the wall f and extends longitudinally of the path of the slide and a suitable distance [laterally of the said path. The plate g extends over'and completely covers the plates 61 and I e and closely overhangsthe path of the slide, as at g. The plate 9 forms, therefore, a guard arranged to exclude dust, dirt, 850., from between the plates 01 and e, from between the plate 6 and the wallf, and from between the plate d and the slide, and the walls of the recess f prevent strain upon the securing devices h by any friction possibly occurring between the top of the slide and the under side of the slide-overhanging portion g of the plate 9 during the operation of the slide, and obviously the portion g of the plate g is instrumental in preventing upward displacement of the slide.

The vertically-adjustable plate'e is provided upon its slide facing side with twosurfaces e', which slope downwardlytoward and face the path of the slide. The sloping surfaces 6' are arranged a suitable distance apart longitudinally of the said plate. The laterally-adj ustable plate (2 is provided on its back side with two surfaces d, which slope downwardly toward the path of the slide and are arranged a suitable distance apart longitudinally of the said plate. The surfaces (Z correspond with and face and are engaged by the different sloping surfaces e, respectively, of the plate a. It will be observed, therefore, that the plate e, having the sloping surfaces 6, forms a wedge, which is arranged with its thicker portion lowermost and is interposed between the sloping surfaces of the plate d and the fixed wall f, and that an elevation of the wedgeforming plate 6 when the plate d is free to be readjusted laterally results in an actuation of the said plate cZ laterally toward the path of the slide, and the plate at when it has been properly adjusted relative to the said path is secured in the desired adjustment. The means employed for securing the laterally-adjustable plate d in the desired adjustment comprise not only the plate 6 and means which secures the said plate 6 in the desired adjustment, but also two verticallyarranged bolts 70, which extend through holes g ,formed in and extending vertically through the plate g (see Figs. I and Ill) into the said plate cZ, engaging correspondingly-arranged screw-threaded holes (1 formed in the upper portion of the said plate d. (See also Fig. V.) The holes 9 are elongated toward the path of the slide, as shown very clearly in Figs. 1 and III, to accommodate a readjustment of the plate cZ relative to the said path. Obviously, therefore, the side-bearing-forming plate (Z is rendered free to be readjusted or secured in the desired adjustment, according as the bolts 7r. are loosened or tightened relative to the plate g, and the said plated is drawn tightly against the under side of the plate 9 or loosened relative to the said plate g, according as the bolts k are operated to tighten or loosen them relative to the plate 9.

The laterally-adjustable plate d is provided at its ends or a suitable distance apart longitudinally of the plate with two laterallyprojecting flanges (1 which are arranged preferably at right angles to the plate and extend across opposite ends, respectively, of the wedge-forming plate 6. The inner sides of the flanges (Z as shown in Figs. I and V, closely overlap vertical surfaces f formed on the wallf, so as to prevent displacement of the plate cZ longitudinally of the path of the slide and relative to the wedge-forming plate e, and hence the said plate d cannot be displaced endwise by any possible friction between the plate d and the slide during the operation of the slide, and strain upon the bolts is avoided by such friction, and the bed or its wall f is not worn by the ends of the said plate d.

The laterally-adjustable plate d is provided in the upper edge thereof and centrally between its ends with a recess CZ, which extends transversely of the said edge at right angles to the path of the slide and is engaged by a correspondingly-arranged tongue g which is formed upon and depends from the rsaaeae under side of the slide-overhanging plate g and extends from within the recess d over the wedge-forming plate 6 into the wall f, which is provided in the top thereof with a recess fflengaged by the said tongue. The mutually-engaging tongue g and recessf are instrumentalin preventing displacement of the plate g longitudinally of the path of the slide and are consequently instrumental also in avoiding strain upon the devices employed in securing the said plate to the wall f, and the said tongue 9 and the recess (Z are instrumental in preventing displacement of the plate cZ longitudinally of the travel of the slide.

The wedge-forming plate e is provided centrally between its two sloping surfaces 6, as shown more clearly in Fig. II, with a vertically-arranged stud Z, which is screwed into or otherwise fixed to the upper edge or top of the said plate. The stud Zextends upwardly and loosely through a correspondingly-arranged hole 9 formed in the plate g. A nut m is mounted on the stud Z at the top of the plate g, and obviously the stud Z, and consequently the plate 6, is elevated or lowered, according as the nut is turned in one direction or the other, and the plate 6 is tightened or loosened relative to the plate 61, according as the said plate 6 is raised or lowered. Two vertical screws 0 extend into engagement with the top of the wedge-forming plate 6 and are arranged a suitable distance apart longitudinallyof the said plate at opposite sides, respectively, of the stud Z. The screws 0 extend into engagement with the plate 6 through correspondiugly-threaded vertical holes 9 formed in the plate g, and lock-nuts p are mounted on the said screws at and contiguous to the upper side of the plate g.

By the construction hereinbefore described it will be observed that withdrawal of the screws 0 upon loosening the lock-nutsp accommodates a lifting or raising of the plate e by properly manipulating the nutm to readjust the plate d, When the latter is rendered free to be readjusted relative to the path of the slide.

The upper portion of the wedge-forming plate e is enlarged in thickness, as at 9 centrally between the sloping surfaces 6 of the said plate, toward the plate d to accommodate the provision of the stud Z, as shown in Figs. II and V, and the said plate d has its upper portion, recessed, as at d .to accommodate the location of the said enlarged portion of the plate 6.
